Our panel of experts are, clockwise from top left: David Long, Mark Malinoski, Zane Scott, and Mark Simons. As you reflect on the past year, what is one new insight you had regarding systems engineering and/or model-based systems engineering? Where is model-based systems engineering headed at this point in our …

Complexity is a term that not only defies any disciplined usage in our usual discourse, but also lacks a rigorous definition even in academic circles. It is often confused with complicatedness and is popularly invoked whenever we see many parts arranged in intricate relationships and interacting in hard-to-predict ways. In …

In model-based systems engineering, we tend to focus on requirements and design, but how many MBSE implementations consider aligning design with verification and validation (V&V)? The Vitech systems metamodel is especially capable of supporting V&V activities throughout the development lifecycle on either side of the “V.” Let’s take a look. …

We talk a lot about “modeling language” in the world of systems engineering. That phrase gets used in a variety of ways with different meanings. It is the focus of discussions of standards. And yet, the variety of the usage of “modeling language” has some deleterious effects on the understanding …
